send oneTHE PENNY MAP / FOUND ONE?
Found a penny card?
Mark the spot.
Yes, that is a real penny. I taped it to a business card and left it where somebody like you would trip over it. Five hundred of them, around the Bay Area, in November. This map is where they turned up.
Tap the spot where you found yours. Ten seconds, no account, no catch. The penny is yours either way. Keep it, spend it, or send it back. Sending it back is sort of the whole experiment, so no pressure. Some pressure.
Counting the pins…
The map never asks your phone where you are. You show it.
PIN YOUR PENNY
PINNED
You are on the map.
Now the fun part. That penny could come home. One cent, on the public ledger, from someone who found it on the ground. That is the best possible version of this experiment.
Or leave the card for the next person. The penny is optional, the card still works. Pin another one
